So you want to create your own .NET runtime?
summary
Creates an interpreted .NET runtime in plain C from a tiny starter file, based on DotNetAnywhere, by parsing PE headers, the CLR header, metadata streams and ~# tables, mapping RVAs into allocated memory and loading table rows; implements an IL interpreter that supports at least the ret opcode and successfully runs a simple HelloWorld DLL (methoddef count = 2, CLR version 4.0.30319). Uses fopen/malloc/memcpy, manual pointer arithmetic and hard‑coded table widths, claims the core can be prototyped in about one hour.
